POROUS FILM AND LAMINATED POROUS FILM

摘要

There is provided a porous film, comprising a polymer having a thermal decomposition initiation temperature of 200° C. or more and a raw material monomer thereof, wherein a ratio of the raw material monomer is 0.05% by weight or more and 5% by weight or less based on the total weight of the polymer and the raw material monomer; and a laminated porous film, wherein the porous film and a porous film containing a thermoplastic resin are laminated.
